ABSTRACT:
A method and apparatus for aligning laser cavity and transport optics with one or more targets is disclosed. An alignment beam is deflected from its initial path and is rotated about the alignment axis in an annular sweep. Detectors circumferentially located about a desired point located relative to the target are responsive to the intensity of the rotatig alignment beam for producing corresponding outputs. The cavity optics and transport optics may be adjusted relative to the target so that the output of the detectors are the same thereby assuring that the various respective optics are aligned with the target.
